After sentencing, Mr Connor said the abuse had affected her emotionally and affected her relationships. She had struggled with low self-esteem, he said, and had been on anti-depressants and suffered “night terrors.”

Pleading for a lesser sentence on behalf of Cartwright, defence barrister Dafydd Roberts said the offence was a historic one and his client had not re-offended in the same manner since.

Passing sentence, the Judge, Timothy Petts said: “This is a serious offence not only because of what you did but also her very young age at the time and the considerable effects it has had on her since. This was a serious and disgusting offence for which immediate custody is appropriate.”

Cartwright was was also ordered to sign on the sex offenders’ register indefinitely.
